Can a Microsoft 365 Tenant Have Multiple SharePoint Root Sites?
Question details
The user wants to know if it is possible to configure multiple SharePoint root sites with different verified domains within a single Microsoft 365 tenant.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Configuring domains and root URLs for organizational SharePoint sites in Microsoft 365.
- Observed behavior
- The tenant uses a single default domain for its top-level root site, and adding a new verified domain does not automatically create a second SharePoint root URL.
Before making structural changes to your tenant's domains or sites, ensure you are logged in with Global Administrator or SharePoint Administrator privileges in the Microsoft 365 admin center.
Create Additional SharePoint Sites Under the Default Domain
Since multiple root domains are not supported in one tenant, the standard approach is to build additional site collections under your single existing SharePoint domain.
Microsoft 365 architecture restricts each tenant to exactly one top-level SharePoint root URL, tied to the default initial domain (e.g., yourcompany.sharepoint.com). While you cannot have multiple root domains, you can create an unlimited number of sub-sites and site collections under this primary domain.
Log in to the Microsoft 365 admin center, expand the left navigation menu, and select the SharePoint admin center.
Navigate to 'Sites' and then 'Active sites'. Click on the 'Create' button to start provisioning a new site, choosing either a Team site or a Communication site based on your needs.
Fill in the required site name, owner, and language settings. The new URL will automatically be appended to your existing default SharePoint domain (e.g., domain.sharepoint.com/sites/newsite).
Set Up a Separate Microsoft 365 Tenant
If your organization strictly requires an entirely independent root domain for a specific SharePoint site (such as for a distinct subsidiary), you must provision a completely separate Microsoft 365 tenant.

Frequently Asked Questions
Can I change my existing SharePoint root site domain?
Yes, Microsoft allows organizations to rename their SharePoint domain using PowerShell (e.g., changing from oldcompany.sharepoint.com to newcompany.sharepoint.com). However, this only replaces the existing root domain; you still cannot have multiple top-level domains active at the same time within a single tenant.
Does adding a verified domain to Microsoft 365 create a new SharePoint URL?
No. Adding multiple verified domains to your Microsoft 365 tenant allows you to use those domains for user email addresses (Exchange) and logins, but it does not generate additional SharePoint root sites. SharePoint will continue to use the tenant's default initial domain.
How do organizations manage different brands in one tenant without multiple root sites?
Organizations typically use Hub Sites to group and organize related sites under the single root domain. This allows you to apply consistent branding, customized navigation, and centralized search across all sites belonging to a specific brand or department, even though they share the same base URL.
